Title: 부들(Typha orientalis)솜을 이용한 마스크(Mask) 제조 방법
IPC: A62B18/02
Filed: 2009-11-02
Abstract: [배경기술] 일반적인 마스크는 호흡기를 통해 인체 내로 들어가는 발암물질인 포름알데히드(formaldehyde)를 제거하지 못한다. 이러한 문제점을 해결하고자 천연의 부들 암꽃을 그대로 또는 가공하여 마스크 재로 이용하는 것이다 
     [해결하고자 하는 과제] 호흡기를 통해 인체 내로 들어가는 공기 중의 발암유발 물질로 지목된 포름알데히드(formaldehyde)를 차단한 마스크로 호흡을 통해 야기되는 정서적 불안, 기억력 상실, 정신집중 곤란, 위의 손상,  암  유발, 감기 등의 질병 예방을 가져올 수 있도록 제조하는데 그 목적이 있다. 
     [과제의 해결 수단] 식물성 부들솜을 마스크의 주재료로 이용하는데 그 특징이 있다. 
     [효과] 천연소재인 부들솜을 마스크의 원료로 이용함으로서 호흡기를 통해 유입될 수 있는 발암유발 물질인 포름알데히드(formaldehyde)를 제거하여 호흡을 통한 정서적 불안, 기억력 상실, 정신집중 곤란, 위의 손상,  암  유발, 감기 등의 질병 예방으로 인체의 건강증진을 꽤 할 수 있다. 
     [색인어] 
     1. 부들 3)  : 학명은 부들(Typha orientalis)과로 다년초다. 연못 가장자리와 습지에서 자란다. 높이 1∼1.5 m이다. 뿌리줄기가 옆으로 벋으면서 퍼지고 원주형이며 털이 없고 밋밋하다. 잎은 나비 5∼10 mm이고 줄기의 밑 부분을 완전히 둘러 싼다. 꽃은 6∼7월에 피고 1가화(一家花)이며 원주형의 꽃 이삭에 달린다. 위에는 수꽃이삭, 밑에는 암꽃이삭이 달리며, 두 꽃 이삭 사이에 꽃줄기가 보이지 않는다. 포(苞)는 2∼3개이고 일찍 떨어지며 꽃에는 화피(花被)가 없고 수꽃에서는 화분(花粉)이 서로 붙지 않는다. 열매이삭은 길이 7∼10 cm이고 긴 타원형이며 적갈색이다. 잎은 방석을 만들고, 화분은 지혈(止血)·통경(通經)·이뇨제(利尿劑)로 사용한다. 잎이 부드럽기 때문에 부들부들하다는 뜻에서 부들이라고 한다. 한국·일본·중국·우수리·필리핀 등지에 분포한다. 잎의 나비가 1.5∼2 cm이고 화분이 4개씩 합쳐지는 것을 큰 부들(T. latifolia)이라고 하며, 북반구의 온대지방에 퍼져 있다. 애기부들(T. angustata)은 수꽃이삭과 암꽃이삭 사이에 꽃줄기가 나타나는 것이 다르고, 유럽·아시아의 온대와 난대 및 지중해 연안에 분포한다. 
     2. 부들꽃 : 부들 줄기 꼭대기에 수꽃이 달리고 그 아래 원주형으로 빽빽이 암꽃이 달린다. 수꽃은 포황이라고 하는데 한약재로 쓰인다.  암꽃 은 소시지처럼 생겼는데 굵기는 지름이 3cm 정도고 길이는 15cm 내외다. 이  암꽃 이 본 발명의 요체로 모양은 아래의 사진과 같다. 
     
       
     
     
       
     
     3. 부들솜 : 위 2.항의 암꽃을 부풀린 것이  부들솜 으로 아래의 사진과 같다 
     부들 암술을 채취하여 용기에 보관해 두면 자연적으로 아래의 사진과 같이 부풀어 오른다. 
     
       
     
     4. 포름알데히드(formaldehyde) 4) 
 
     화학식은 HCHO다. 자극적인 냄새가 강한 기체이며, 분자량:30.0, 녹는점 -92 ℃, 끊는점 -21 ℃, 비중 0.815이다. 시체방부용으로 잘 알려진 포름알데히드는 사람이 마시면 매우 위험하다. 공기흡입, 피부접촉, 음식섭취의 형태로 접촉할 수 있으며 30ppm에선 질병증세가 나타나며 100ppm 이상에서 1분 이상 노출하면 심각한 영향을 받게 된다. 여기서 증세나 영향이란 정서적 불안, 기억력 상실, 정신집중 곤란, 위의 손상,  암  유발 등을 말한다. 이 물질은 옷, 침대, 가구, 페인트칠한 벽, 자동차 배기가스에서 공기 중으로 나오며 저절로 생성되기도 한다. 쉽게 생성되기도 하지만 분해도 활발히 일어난다. 강한 자극적인 냄새가 나며, 피부에 염증을 일으키고 점막을 침해한다. 물에 잘 녹으며, 보통 35∼38％ 농도의 수용액으로서 
     
       
     
     포르말린이라는 이름으로 시판되어 의약에 쓰이고 있다. 
     포름알데히드는 생리대, 새 옷, 전자제품, 매니큐어, 화장품, 건축 마감재, 가구, 소독제, 방부제, 세척제, 방충제, 페인트 등에 첨가된다. 자극적인 냄새가 나며 독성이 매우 강해 전 세계적으로 암 유발물질로 지정하였다. 두통, 피로, 피부발진, 기억력감소, 불면증, 눈 질병, 중추신경계통질병, 신경이상 등등이 있고 심해지면 피부암에서 사망까지 이를 수 있는 물질이다. 화장품이나 물티슈에 많은 회사들이 방부제로 쓰고 있지만 매우 소량만 들어가 안전하다고 말하고 있다. 하지만 우리는 이런 제품을 하루에도 수십 가지만지고 바르며 사용하기 때문에 적은 양이 쌓여서 체내에 축척될 경우 위험하지 않다고 말하기 어려울 것이다. 사람이 죽으면 2일이면 부패가 시작된다고 하는데 요즘은 일주일이 넘어야 부패가 시작된다고 한다. 그 이유가 독한 방부제를 지속적으로 접하고 있어 신체 내에 축척되기 때문이라고 한다. [포름알데히드로 인한 피해양] 0.04 ppm : 아토피성 피부염 및 신경조직 자극 0.05 ～ 0.1 ppm : 냄새를 느낌 0.2 ppm : 눈에 자극이 시작됨 0.25 ～ 0.3 ppm : 호흡기 장애 시작됨 0.5 ppm : 목에 자극이 시작 2 ～ 3 ppm : 눈을 찌르는 듯 한 고통이 생김 4 ppm : 눈물이 나옴 10 ～ 20 ppm : 정상적인 호흡이 곤란 30 ～ 50 ppm : 급성 중독 증상, 독성 폐기종으로 사망 가능

Abstract: The present invention relates to a fixed receiving system (A) for a radio relay channel system for transmitting, on a fixed network, information transmitted on a unique wavelength U by a plurality of transmitters generally associated with measurement sensors, the transmitters being dispersed over a geographic area, to the receiving system (A) for the collection of all of the information transmitted in said geographic area. The system comprises at least two antenna (1)-receiver (2) pairs (I, II), each receiver (2) of said pair (I, II) only being associated with the single antenna (1) of the same pair (I, II), the output of each receiver (2) being connected to a single information acquisition controller (4), the antenna (1) of one pair (I, II) being placed at a distance of at least U/4 of the antenna (1) of the other pair (I, II), in order to protect against the effects of null spots resulting from the mutual cancellation of waves originating from the same transmitter but having followed different propagation paths, and having undergone different and even opposite transformations in terms of amplitude and phase.
